J cup swimwear sits near the top of Brava's swim range, and the brands that build it well are a very short list. At J cup, look for encapsulation: each side of the bust supported independently in a deep, structured, underwired cup, rather than compressed flat across.
Fit at J cup
Look for long channelled underwires that clear the side breast tissue, firm non-stretch cup fabric, and wide, adjustable straps to carry the weight. Side support panels stop the bust migrating outward when you're active in the water. At this size, a swim top fitted correctly in your bra size makes the difference between constant readjusting and genuine security.
